Embodiment Construction

[0045] Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0046] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Throughout the specification, the same reference numerals refer to the same elements.

[0047] It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another ele...

Abstract

A display device having a sensing unit includes a first substrate having a plurality of test spacers, and a second substrate having a plurality of sensing unit test lines facing the test spacers, respectively. The surface heights of the sensing unit test lines are different from each other. The heights of the test spacers are substantially the same. The second substrate further includes a plurality of height difference portions formed under the sensing unit test lines, and the number of height difference portions formed under the sensing unit test lines is different for different sensing unit test lines.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2006-0006733 filed on Jan. 23, 2006, the entire contents of which are hereby incorporated by reference. technical field [0002] The invention relates to a display device, a liquid crystal panel assembly and a test method for the display device. More particularly, the present invention relates to a display device having a sensor unit, a liquid crystal panel assembly, and a method of testing the sensor unit of the display device. Background technique [0003] A liquid crystal display (LCD) includes a pair of panels provided with a pixel electrode and a common electrode, and a liquid crystal layer having dielectric anisotropy interposed between the panels. The pixel electrodes are arranged in a matrix and connected to switching elements such as thin film transistors (TFTs) such that the pixel electrodes receive image data voltages row by row. The common electrode covers the entire surface of one of ...
